What does AIX mean?

Advanced Interactive eXecutive
The IBM AIX OS was originally based on UNIX System V with 4.3 BSD-compatible extensions. The name AIX stands for Advanced Interactive eXecutive, which is partially derived from the Interactive Systems Corporation name.

What is an AIX frame?

IBM Power Series hosts (frames) are large servers that support virtualized “partitions”. These partitions run operating systems. An IBM Power Series host can be partitioned into logical partitions (LPARs) in the following ways: Dedicated mode: Processors are assigned entirely to partitions.

Where is AIX used?

The companies using IBM AIX are most often found in United States and in the Computer Software industry. IBM AIX is most often used by companies with 50-200 employees and >1000M dollars in revenue.

What is LPAR in IBM?

An LPAR is a subset of the processor hardware that is defined to support an operating system. An LPAR contains resources (processors, memory, and input/output devices) and operates as an independent system. Multiple logical partitions can exist within a mainframe hardware system.

Is AIX based on Linux?

AIX is based on UNIX System V with 4.3BSD-compatible extensions. The AIX family of operating systems debuted in 1986, became the standard operating system for the RS/6000 series on its launch in 1990, and is still actively developed by IBM. It is currently supported on IBM Power Systems alongside IBM i and Linux.

Why do people use AIX?

AIX was the first operating system to utilize journaling file systems, and IBM has continuously enhanced the software with features like processor, disk and network virtualization, dynamic hardware resource allocation (including fractional processor units), and reliability engineering ported from its mainframe designs.


Summary. Power Systems uses the term Logical Partition (LPAR), which is a vague non-descriptive term and the rest of the computing world uses Virtual Machine (VM).

Is LPAR a hypervisor?

PR/SM is a type-1 Hypervisor based on the CP component of VM/XA that runs directly on the machine level and allocates system resources across LPARs to share physical resources. It is a standard feature on IBM System z only.
